The statistical behavior of 11-12-GHz attenuation at different times of day, as observed in the Sirio experiment
Abstract
Measurements of the precipitation attenuation of the 11-12-GHz signal (EIRP 44.7 dBm) of the Sirio satellite, obtained at Fucino, Lario, and Spino d'Adda, Italy, during 1978-1982, are analyzed statistically; and their implications for satellite direct broadcasting of TV programming are discussed. The data are presented in histograms showing attenuation at each station at different times of day. It is found that a DBS-TV receiver in northern Italy is likely to encounter 13-14 h of service interruuption per year in the afternoon hours but only 5-6 h in the morning, whereas the interruption probability in central and southern Italy varies less over the day.
